SPEAKER PLACEMENT
For the best stereo image, place a pair
of speakers so the distance between
them is about the same as the distance
between the listening area and the
point halfway between the speakers.
If you must place the speakers farther
apart, turn them slightly inward. If you
must place them closer to each other,
turn them slightly outward. Experiment
with your speakers’ placement to find
the best location for them.

CONNECTIONS
Your local Radio Shack store has a
wide selection of speaker wire. We rec-
ommend you use color-coded or
marked wire to help you correctly con-
nect the wire. Most color-coded wires
have a stripe running down one of the
conductors and marked wires have
ridges along one of the conductors.
With the speakers in their approximate
locations, measure the distance from
each speaker to your receiver/amplifi-
er.
Use 18-gauge speaker wire (not sup-
plied) for distances up to 50 feet. For
greater distances, use 16-gauge wire
(not supplied).
Note: For maximum bass response
and the best overall performance, con-
nect your speakers so they are in
phase (+ to +, and – to –).
1. Separate the wire’s two conduc-
tors at both ends for a length of
about 4 inches.
2. Strip the insulator from the ends of
each conductor to expose 1/4-inch
of metal wire and twist the loose
strands.
3. Press the tab on the left speaker’s
negative (–) terminal and insert
one of the wire ends. Then release
the tab.
4. Press the tab on the left speaker’s
positive (+) terminal and insert one
of the wire ends. Then release the
tab.
5. Using the speaker wire’s code as
a guide, connect the wire from the
left speaker’s negative (–) terminal
to the receiver/amplifier’s left neg-
ative (–) terminal.
Then connect the wire from the left
speaker’s positive (+) terminal to
the receiver/amplifier’s left positive
(+) terminal.
6. Repeat Steps 3-5 to connect the
right speaker.

CARE AND MAINTENANCE
Your STS 65 Two-Way Bookshelf Speaker is an example of superior design and
craftsmanship. The following suggestions will help you care for the speaker so you
can enjoy it for years.
Keep the speaker dry. If it gets wet, wipe it dry immediately. Liquids
might contain minerals that can corrode the electronic circuits.
Use and store the speaker only in normal temperature environ-
ments. Temperature extremes can shorten the life of electronic de-
vices and distort or melt plastic parts.
Keep the speaker away from dust and dirt, which can cause prema-
ture wear of parts.
Handle the speaker gently and carefully. Dropping it can damage
circuit boards and cases and can cause the speaker to work improp-
erly.
Wipe the speaker with a damp cloth occasionally to keep it looking
new. Do not use harsh chemicals, cleaning solvents, or strong de-
tergents to clean the speaker.
Caution: You might permanently damage your speaker by cleaning it with a vacu-
um cleaner. Instead, use a feather duster or a soft cloth.
Modifying or tampering with the speaker’s internal components can cause a mal-
function and might invalidate your speaker’s warranty. If your speaker is not per-
forming as it should, take it to your local Radio Shack store for assistance.
